Note As shown in the table, an American worker employed in Japan can only be covered by U.S. Social Security if he or she works for a U.S. employer. A U.S. employer includes a company organized under U.S. or state law, a partnership if at least two-thirds of the partners are based in the United States, a person residing in the United States, or a fiduciary company if all directors are based in the United States. It is also a foreign subsidiary of a U.S. employer when the U.S. employer entered into an agreement with the Internal Revenue Service, pursuant to Section 3121 (l) of the Internal Revenue Code, to pay Social Security taxes for U.S. citizens and residents employed by the subsidiary. The United States currently has social security agreements with Canada, Chile, South Korea, Australia and most of Western Europe.

This agreement, which came into force on 1 October 2005, avoids the double taxation of social contributions during the contribution phase and provides guidance for applications for benefits under Japanese social security and pension plans. The Japanese systems covered are generally work-related and mandatory, for example. B k`seinkin and kokumin nenkin. If you do not agree with the decision on your entitlement to benefits under the agreement, contact a U.S. or Japanese social security office. The people there can tell you what you need to do to appeal the decision. Help fill the gaps in benefit protection for workers who have shared their careers between the United States and another country but have not worked long enough in one or both countries to qualify for social benefits. Totalization allows workers to combine work credits from both countries to receive benefits. The amount of the benefit paid is proportional to the amount of credits acquired in the paying country.

In the United States, after the signing of the agreement, the President will submit the agreement to Congress, where it will have to be reviewed for 60 days of session. If Congress does nothing during this period, the agreement can move forward. On October 1, 2005, Japan was the last country to be included on the list of countries with which the United States of America has social security agreements. To date, the United States has concluded 21 of these agreements, the oldest of which is the Treaty with Italy – it came into force in 1978. In the meantime, the United States has concluded social security agreements with Germany, Switzerland, Belgium, Norway, Canada, the United Kingdom, Sweden, Spain, France, Portugal, the Netherlands, Austria, Finland, Ireland, Luxembourg, Greece, South Korea, Chile, Australia and Japan. The Data Protection Act requires us to inform you that we are entitled to collect this information until Section 233 of the Social Security Act. Although it is not mandatory for you to provide the information to the Social Security Administration (SSA), a coverage certificate can only be issued if an application has been received. The information is necessary to enable the SSA to determine whether, in accordance with an international agreement, the work should only be covered by the U.S. social security system.

Without the certificate, work can be taxed in both the United States and foreign social security schemes. Self-employed workers who, in the absence of the agreement, would have to pay social security contributions to both countries are subject to special rules (see table below). For the United States, the agreement includes Social Security taxes (including Medicare`s U.S. share) and social security, disability and survival benefits. It does not cover benefits under the U.S. Medicare program or the security supplement.
